Le barotraumatisme sinusien est le deuxième en fréquence après celui de l'oreille moyenne. Le sinus frontal est le plus touché. C'est une pathologie rare et spécifique. Nous rapportons le cas d'un patient de 26 ans présentant suite à une plongée des douleurs frontales gauche intense avec épistaxis homolatérale. Le scanner a montré un hémosinus frontal gauche. L'évolution était bonne après traitement. Les barotraumatismes du sinus frontal sont des accidents liés aux variations de la pression ambiante. L'épistaxis est un signe de gravité. Le scanner a un intérêt dans la recherche des facteurs favorisants et la surveillance. Le traitement vise à supprimer la symptomatologie et la cause favorisante. Les barotraumatismes sinusiens constituent un accident rare, les complications orbitaires et encéphaliques sont exceptionnelles. Leur traitement curatif se confond avec celui de la pathologie causale.

Introduction Mandibular localization of tuberculosis is rare and represents less than 2% of skeletal locations. Its clinical and radiological features are not specific. In this paper, we report a case of fortuitous discovery of mandibular tuberculosis after a histopathological analysis of the surgical resected specimen during surgical management of an ameloblastoma. Presentation of case A 50-year-old female patient was admitted to our department with a 2 years history of left cheek swelling, the clinical examination revealed a left cheek swelling, extending from the mandibular angle to below of temporomandibular joint, measuring approximately 5 cm in diameter. The swelling was firm to hard in consistency, and cervical lymphadenopathy of submandibular region was noticed. Computed tomography (CT) scan revealed a large multiloculated osteolytic expansive lesion measuring 56 ∗ 48 ∗ 53 mm. An interrupting hemimandibulectomy, was performed from the left parasymphys opposite to 33 tooth, extending to the left temporomandibular joint. The histopathological findings confirmed the diagnosis of ameloblastoma, with negative free margin. A mandibular and lymph node tuberculosis were associated with giant cells and caseating necrosis. The patient was successfully treated with a standard anti-tuberculosis therapy. Discussion Ameloblastoma is a benign odontogenic tumor, 80% of these tumors are found in the mandible. Primary mandibular tuberculosis is an extremely rare entity. Its clinical presentation is not specific. Radiologically, tuberculosis has no characteristic appearance. However, it is possible to evoke it in case of a lytic image of the mandible. The positive diagnosis is based on histology. The treatment is medical, but surgery is necessary for some cases. Conclusion The association between ameloblastoma and mandibular tuberculosis represents an extremely rare entity. Mandibular tuberculosis is rare and should be considered as a possible diagnosis in pandemic areas.

Introduction The internal jugular vein thrombosis is usually due to intravenous drug abuse, prolonged central venous catheterization or deep head-neck infections or trauma. Related malignancies, or inflammatory etiologies are described. Our case is interesting by the ingestion of a sewing needle that passes from the pharynx to the internal jugular vein via migration, leading to life-threatening complications: deep neck space infection and internal jugular vein thrombosis. Case report We report a case of a 40 years old patient, for acute cervical cellulitis in a context of odynophagia and fever, a CT scan revealed a jugular vein thrombosis, penetrated by a metal density foreign body. The diagnosis of ingested foreign body complicated by cervical cellulitis and thrombosis of the internal jugular vein was made. The patient underwent neck surgery with intravenous antibiotics. The postoperative course was uneventful, after one year of follow-up, no complications have been observed. Discussion no consensus has been reached concerning the management of postoperative and post traumatic vein thrombosis. Taking into account the risk of extension of the thrombus and the hemorrhagic risk each case should involve discussions among a multidisciplinary team. Conclusion The internal jugular vein thrombosis is a rare complication of ingested foreign bodies which may lead to life threat. The early diagnosis and adequate treatment of its life-threatening complications may result in excellent prognosis.
